This invention relates to pattern marking machines for use in shoefactories, and more particularly to the construction of the platens ofsuch machines.

Pattern marking machines for shoes, as is well known to those familiarwith the art, usually comprise a base mounting a template card uponwhich the shoe element to be marked is placed, a movable printing headadapted for the interchangeable reception of marking dies, and a meansfor inking the die.

It is oftenessential in marking shoe elements, particularly quarters,Vamps and tips, that the pattern applied be differently placed uponsimilar elements of different size shoes in order that the shoe stock inits completed state may have an appearance of proportion. The usualshoemarking machine provides no means of adjustment save possibly arough adjustment of the die carried by the printing head, and thisadjustment is both diflicult to make and impossible of any greatvariation. It is often necessary that the pattern be displaced at oneend of the section While held in a corresponding position at itsopposite end, in various sizes. In marking a changed size, it is oftennecessary that the marking be shifted both longitudinally andtransversely. In corresponding markings for rights and lefts it isessential that the markings be correspondingly placed.

An important object of the present invention is the provision ,of aplaten which is so constructed that adjustments made for varying sizesand types may be accurately determined, and these adjustments made witha minimum of time loss and effort.

A further object of the invention is the production of an apparatus ofthis character which may be readily produced and which will be durableand efficient in service.

'These and other objects I attain by the construction shown in theaccompanying drawings wherein, for the purpose of illustration. I haveshown a preferred embodiment of my invention and wherein:

Fig. 1 is a plan view of a shoe-marking machine constructed inaccordance With my invention showing one adjustment of the platen;

Fig. 2 is a section on line 22 of Fig. 1;

Fig. 3 is a plan View of the platen removed;

Fig.4 is a section on line 44 of Fig. 3;

Fig. 5 is a section on line 55 of Fig. 3;

Fig. 6 is a combined perspective of the several parts forming theplaten;

Figs. '7 and '8 are bottom perspectives of two different forms of platenface; and

Fig. 9 is a perspective of a template.

Referring now more particularly to the drawings, the numeral I generallydesignates a platen bed; i l, a printing head; I2, a die carriedthereby; and I3, an inking device for the head. Seated upon the platenbed is a platen comprising a base i4 having upstanding side guides I5and having disposed within a longitudinal slot l6 formed 10 therein ablock i1 adjustable through a screw H3. The block I! is adapted forattachment to a sub-base l9 slidable between the side guides l5 andprovided with upstanding end guides 20. The sub-base 59 has a block 2!slidable in a transverse slot 22 formed therein and adjustable by meansof a screw 23. This block 2! is, in turn, adapted for attachment to aplate 24 having in its upper surfacea longitudinally-extending groove25. A slot opens through the bottom of this groove, as indicated at 26and within this slot is disposed an adjustable block 2'! mountinganangular shifting head 28 which, upon adjustment of the block, movestransversely of plate 24 and grooves 25, this adjustment being effectedby a screw 29.

Mounted in the groove 25 is a slide 30 having an angularly disposed slot3| forv the reception of the angular shifting head 28. The slide 30 fitsthe groove 25 and it will be obvious that ad- 30 justment of the head 28will result in longitudinal shifting of slide 30. This slide has atopposite ends thereof pairs of divergent angular slots 32 and 33. Theplate 24 is provided with a pair of spaced pins 34 disposed at one end35 thereof, and at common distances from the center of the groove 25. 1

Superimposed upon the plate 24 is a divided platen face 35 which mayassume a variety of interchangeably usable forms. In each of Figs. '7and 8, the platen face is divided, the sections 36 in Fig. '7 having atopposite ends of adjacent sides thereof fixed angular blocks 31 whichare adapted to engage in the pairs of slots 32 and 33 respectively. Theinner corner members of the sections 36 are notched as at 38 so that theplates may partake of transverse movement without engaging the pins 34.It will be obvious that by reason of engagement of these angular blocksin the slots 32 and 33, the sections 36 will be separated or drawntogether, dependent upon the direction of longitudinal movement of theslide 30.

The platen face of Fig. 8 has a single set of blocks 39 at the rear endthereof, one block being arranged upon each plate and the blocks beingshiftable about pivots 40. These sections 36a have openings 4| thereinfor the reception of the pins 34 which act as pivots about which thesections 36a may swing (see Fig. 1). Blocks 39 engaging in the slots 33will cause the rear ends of the sections to separate or be drawntogether as the slide 30 is shifted longitudinally.

The upper surfaces of the sections of the platen face have upstandingpins 42 adapted to hold templates 43. As in the case of the platen face,the templates may assume a Variety of forms, two being hereinillustrated, although it will be understood that a template must beprovided for each different form of upper section which is to be marked,such templates having gauges 44 against which the piece to be marked maybe placed. The template illustrated in Figs. 3 and 6 is split, and is ofthe type employed when two similar sections, right and left, are to besimultaneously marked. The template has, along one marginal edge, aseries of size graduations indicated at 45 and adapted for co-actionwith an indicator pointer 46 carried by the sub-base I9, and along asecond marginal edge a series of size graduations 4'! adapted forcoaction with a pointer 48 carried by the base I4. This latter pointer,in the present instance, is illustrated as yieldably mounted in order toaccommodate oscillation or separation of the platen faces. The templateof Fig. 9 is a unitary sheet adapted to engage the pins of both platenfaces and is utilized in marking of larger pieces. The gauge marks 41are provided on this type of template although under some circumstanceswhere a single piece is being marked both gauge marks 45 and 41 may beemployed.

It will be obvious from the foregoing that the platen faces may besimultaneously shifted longitudinally or transversely, may be movedtoward or away from one another, and in special cases may be oscillatedto vary the angle of printing upon the varying sizes. Each of thesemovements may be employed independently of the other, and by use oftemplates having proper gauge marks all adjustments may be rapidly andaccurately made. Since variation of the position and angle of the pieceto be marked with relation to the platen bed will permit placing themarkings upon the piece at any desired point, it will be obvious thatnecessity for a large number of templates such as is ordinarily employedmay be avoided. This means not only that the cost of marking is reducedto a minimum but likewise that the operations of marking where a numberof different sizes are being produced are much simplified and expedited.

The construction is obviously capable of considerable modificationwithout in any manner departing from the spirit of my invention and I,accordingly, do not wish to be understood as limiting myself theretoexcept as hereinafter claimed.
